To all whom 'it may concern:

Be it known that I, IVILL'IAM J. I (neNn, a citizen of the UnitedStates, and a resident of the city of Chicago, county of Cook, and Stateof Illinois, have invented certain new and useful Improvements inSpring-Hinges, of which the following is a full, clear, and exactdescription.

The invention relates to double acting spring hinges for doors and thelike, and more particularly to hinges of the type set forth in the priorapplication, Serial No. 535,951, filed in the United States PatentOftice January 3, 1910, by George WV. Schuster and myself.

The present invention seeks to provide an improved construction of hingeframe and improved fastening means by which the hinge is secured to thedoor.

rlthe invention also seeks to provide an improved ferm of fasteningplate which is adapted to be secured to the door and is arranged todirectly engage the post which is fastened to the floor plate andwhereon the hinge frame is pivoted, to thereby form a more secureconnection between the floor plate and the door, and a constructionbetter adapted to withstand the side pressure brought upon the door inswinging it to and fro.

A further object of the invention is t0 provide a simple and effectiveadjustment for alining the door in central position.

The invention consists in the features of improvement hereinafter setforth, illustrated in the preferred form in the accompanying drawing,and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a longitudinal section of the improvedhinge shown in position upon the door. Figs. 2 and 3 are inverted plansections on the lines 2-2 and 3-3, respectively, of Fig. 1. Fig. 41 is aview of lthe inner end of the hinge. Figs. 5 and 0 are detail views,with parts shown in section on the lines 5-5 and 0--0, respectively, onFig. 1, illustrating the adjusting device for alining the door.

The hinge frame comprises upper and lower parallel bars 1 and 2 formedof strap iron or steel. rl`he lower bar is U-shaped and is provided withnpturned end portions 3 and et, the latter end portion having anoutwardly projecting, horizontal extension 5. The upper bar 1 of theframe overlies the Specification of Letters Patent.

extension 5 and is secured thereto by a rivet G and beyond the extensionthe upper bar is prete ably provided with a down-turned end portion 7which is adapted to abut against the end of a rabbet or recess which iscut in the corner of the door 8 to receive the hinge. The opposite endof the upper frame bar 1 is secured to the up-turned end portion 3preferably by means of a lug 9 on the bar seated in a notch in the upperend of the portion 3. A pair of transverse plates 10 and 11 extendbetween the upper and lower bars and are secured in position by lugs 1Qthereon extending through openings in the bars and headed over, asshown. rI`he plate 11 is arranged closely adjacent the up-turned endportion 1 of the lower bar 2, and the crosspiece 10 is arranged near theinner or pivoted end oi the hinge frame.

A floor plate 13 is adapted to be fixed in position beneath the lowercorner of the door and this pl ate has rigidly secured thereto anupwardly projecting post 111 upon which the hinge frame is pivoted. Thepost is preferably journaled in the upper and lower bars. In the fornishown, a bushing 15 is litted within an opening in the lower bar andforms a bearing for the post. Immediately above the bushing the 'post isprovided with an enlarged portion 10. The reduced upper end ot' the postextends through a bushing 17 which is set within an opening in the upperbar. A dished ring 1S lits over the reduced upper end of the post andrests upon a shoulder 19 thereon. This ring and the bushing 17 aresuitably shaped to receive a row of antis'l'riction balls 2O whichsustain the greater part of the weight of the door.

A spring actuated bolt or plunger 21 is slidably mounted within thehinge frame or easing. This bolt or plunger extends loosely tln'oughopenings formed in the cross bars 10 and 11 and in the up-turned endportion l1 of the lower frame bar. it its inner end, the holt isprovided with a head or yoke 22 which extends between the enlargedportion 10 of the post and the ball-bearing member 18 and which isprovided with a longitudinal slot L3 through which the lportion of thepost between the part 10 thereof and its upper reduced end extends. Thisportion ot the post lits the longitudinal slot 23 and forms a guide forthe inner end of the sliding bolt or plunger.

rlhe outer end of the plunger or bolt 2l Xtends loosely through twotransverse slots Qlland 25 toiined in the cross piece ll and in the endportion fl oli the lower traine bar, as niost clearly shown in 5 and (i.A guide block 2G lits between the vertical pieces t and ll and betweenthe upper and lower bars l and 2, as shown. rEhe outer end o'l' the boltis guided in an opening in this blocx and the latter is adjustable fromside to side to aline the door in closed position.

rillhe adjustment ot the block 2G is effected by a transverse screw 27threaded therethrough. lllashers 28 xed to the ends of the screw engagethe edges ot the parts l and ll so that the screw is held againstlongitudinal. movement. @ne end of the screw is provided with a slottedhead so that the screw niay be rotated in opposite directions to inovethe guide block and the outer end oli the plungei.' laterally in one orthe other direction.

At its inner end the head or yolie 22 on the bolt is provided with adepending lug Q9 iaving a transverse tace which is arranged to engage apair of rollers 30. These rollers are arranged within recesses torinedin tl e enlarged portion lo ot thc post and are mounted opposite sidesof the axis ot the post upon pins 8l, the ends of the pins beingsuitably secured to the enlarged portionI 16 ot the post.

A heavy spring 232 coiled about the plunger' extends between the crosspiece l0 and an adjusting nut 33 inounted upon a screw-threaded portionot the plunger inside of the cross piece ll. When the door is shittel inone or the other direction, one of the rollers BO cooperates with thelugor abutment 2f) to shift the plunger inwardly and conipress thespring VJ hen the pressure on the door is relieved, the spring acts toreturn the door to normal central position and to hold it in suchposition. in its longitudinal shiift the plunger is guided at its innerend upon the post 19 and at its outer end in the guide block 28.

rlhe hinge traine is adapted to be seated in a recess or rabbet cut inthe lower corner of the door 8. A Yfastening plate or strip 3d isprovided with openings tor receiving screws whereby it is secured inposition to the edge ot the recess or rabbet, as shown. rllhe Yfasteningplate preferably extends the tull length ot the hinge traine anch whenthe latter in position; the upper bar l thereof rests against the plateand its down-turned end portion 7 abuts against the end ot' the recess.The horizontal extension 5 ot the l wer bar, the cuter end o the upperbar and. the plate all provided with openings tor receiving a fasteningscrew or screws 3G whereby the outer end oil' the hinge traine issecured in position. The

upper reduced end of the pivot bolt let projects above the Lipper bar lot the hinge traine and the fastening plate 34 is provided with anopening 37, the walls ot which en- ;jgage and bear upon the upper end otthe post. By this arrangement, a niore direct connection is torniedbetween the door and the floor plate, since the fastening plate 34:,which is secured to the door7 directly engages the pivot post risingtroni the floor plate, so that the traine of the hinge is relieved, to aconsiderable extent, oi the side strain brought upon the door inswinging it'to and tro. lret'erably, the opening 37 is slightlyelongated7 as shown in Fig. 3, and the plate 34; is provided with atlowirturned tongue 38 which is adapted to extend through an opening 39in the traine bar l and interlock with the edge thereoll upon thelongitudinal movement ot the traine relatively to the plate. The slot 37perniits this longitudinal 1no\."einent7 but the side walls thereofsnugly engage the upper end ot' the post7 so vthat they torni anadditional bearing tor the post and also serve, as stated7 to relievethe hinge traine troni side strains brought upon the door.

The entire construction is such that in ap* plying the hinge it is onlynecessary to cut a recess in the corner oi the door hai/ing straightplane faces which can be readily formed with two saw cuts. lt is notnecessary thereater to forni additional recesses or rabbets in the edgeof the door. Finishing plates 40, secured to the opposite faces ot thedoor by screws el, extend over and inyclose the hinge traine. Afinishing plate l-Q lits upon the upturned inner end portion 3 cil thelower traine bar 2. rllhis plate is provided with inturned edges 43which slidably engage the edges ot the portion 3. rlfhe inturned edgesat their lower ends rest upon the bar 2 and7 when the hinge is inposition, the door extends over the upper edge ot the plate l2 and holdsit in place.

One of the linishing plates 4G is preterably provided with an openingdel, so that `access is afforded to the adjusting screw 2T. By turningthe latter in one or the other direct-ion, the outer end or the hingetraine and the guide block 26 are relativly adjusted and the door towhich the hinge Jranie is secured can thus be alined or adjustedproperly in its central closed position.

it is obvious that changes in ay be inade in the details set forthwithout departure troni the essentials of the invention as detined inthe claims.
